Shock compressibility of single-crystal silicon in the pressure range $280$–$510$ GPa

The shock compressibility of single-crystal silicon is experimentally studied in the pressure range of $280$ to $510$ GPa. Shock waves are created using Mach's explosive cumulative generators. The parameters of shock waves are determined by the impedance matching method, and single-crystal quartz is used as a reference substance. The results agree well with the ab initio calculation results and with the data obtained using laser shock waves.
